While attending a not so stellar conference, my fellow attendees and I got started on this color app. I originally had this idea when I learned about the cube helix algorithm (look at a d3 example). While I don't think the base algorithm is necessarily the best for contrast, I think it could be tweaked a bit to get a really good color set. I wanted to make an app that would let me explore the possibilities as well as having an opportunity to get to know Angular better.
